Question

所以，我是MEAN堆栈的新手，我试图播种MongoDB。我正在使用Mongoose与数据库进行通信，并且有大量文档表明我应该能够使用填充的JSON文件进行播种。

我尝试了什么：

node-mongo-seed ;非常简单，但在数组末尾始终抛出错误。（也许缺少的bson模块有问题？）

Successfully initialized mongoose-seed
[ 'app/models/locationsModel.js' ]
Locations collection cleared
Error creating document [0] of Location model
Error: Location validation failed
Error creating document [1] of Location model
Error: Location validation failed
Error creating document [2] of Location model
Error: Location validation failed...

mongoose-seed ;同样非常简单，基本上在导出到数据库之前将JSON对象放入变量中。有希望，但......更多错误......

            {
                "days": "Sunday",

        ],
        "reviews": [

                "rating": 5,

                "author": "Jacob G.",
                "timestamp": "new Date('Feb 3, 2016')",
                "body": "Whoa! The music here is wicked good. Definitely going again."
            },
            {
                "rating": 4,
                "id": ObjectId(),
                "author": "Tom B.",
                "timestamp": "new Date('Feb 23, 2016')",
                "body": "I asked to play her a tune. She said no."
            }
        ]
    }
}

所以，我的想法是它可能是JSON结构中的语法错误，但是玩弄它并没有产生任何真正的解决方案（或者我可能错过了它？）。我的JSON示例：

var mongoose = require('mongoose');

var subHoursSchema = new mongoose.Schema({
    days: {type: String, required: true},
    opening: String,
    closing: String,
    closed: {type: Boolean, required: true}
});

var subReviewsSchema = new mongoose.Schema({
    rating: {type: Number, required: true, min: 0, max: 5},
    author: String,
    timestamp: {type: Date, "default": Date.now},
    body: String
}); 

var locationSchema = new mongoose.Schema({
    name: {type: String, required: true},
    address: String,
    rating: {type: Number, "default": 0, min: 0, max: 5}, 
    attributes: [String],
    coordinates: {type: [Number], index: '2dsphere'},
    openHours: [subHoursSchema],
    reviews: [subReviewsSchema]
});

mongoose.model('Location', locationSchema);

此外，我不完全确定如何在JSON中指定子文档（假设我可以让播种过程首先正常工作）。

这是我的模特：

choco install python2
choco install visualstudioexpress2013windowsdesktop

非常感谢有关如何解决这些问题的任何见解。谢谢！

Answer 1

您可以使用mongoimport

在CLI中填充MongoDB

它会将JSON文件加载到指定的MongoDB实例＆amp;集合，您只需要在执行之前运行mongod实例。

以下是使用mongoimport的{{3}}。

你JSON没有流动你的架构。

修复你的JSON：

您可以使用mongoose-data-seed编写自己的种子脚本，以便与您的猫鼬模型进行交互： https://github.com/sharvit/mongoose-data-seed

Answer 3

我在项目上解决了此问题，方法是使用<soapenv:Body> <bean:getPersonByUserIdIP> <bean:attribute>name</bean:attribute> <bean:attribute>address</bean:attribute> <bean:userId>hx52301</bean:userId> <bean:userType/> </bean:getPersonByUserIdIP> </soapenv:Body>`将相关数据转储到扩展的JSON数组格式的文件中，然后使用mongoexport --jsonArray包将其导入到Node应用程序中的POJO格式。然后，我仅使用Mongoose，使用您使用Mongoose创建的正确集合模型，将结果JS数组重新插入数据库中。

为应用程序播种以进行首次运行所需的JSON数据文件被检入到应用程序存储库中。这是一个快速示例，您也许可以适应您的目的：

EJSON

我还建议您研究mongo-seeding。有JS库版本和CLI版本。 here描述了该库的动机。
